Recipes

A recipe is a set of scripts and configuraitons that are used to reproduce experiments. All the steps used to conduct experiments are provided in a self-contained way. Please have a look at the egs directory if you want to build your singing voice systems.

Background

As of Feb. 2020, NEUTRINO, a DNN-based singing voice synthesis tool, has started gaining its popularity in Japan. Because of the powerful DNN-based approach, users can create expressive and natural singing voices even without manual tuning which is typically required to achieve satisfactory quality using the existing tools.

While NEUTRINO is a great tool for creative purposes, it is not open-source software. In fact, there are only a few open-source toolkits to the best of our knowledge. To advance the singing voice synthesis research, we aim to provide a modern DNN-based singing voice synthesis tool for researchers and developers.

That being said, I was just curious to see if I can make a better one than NEUTRINO. We’ll see :)
